摘要：传统的失物招领管理方式主要依靠人工纸质记录，随着失物招领网络信息化建设的不断推进，显然不能满足日益增多的管理需求。为此我们设计出一个有失物信息发布功能、物品认领功能、全景图在线寻物功能集一体的失物招领平台。其相对于传统在线失物招领平台的最大区别在于增加了全景图模式，因其巧妙地融合了虚拟现实技术、数字图像处理技术、计算机图形学和多媒体技术等信息技术，以人机交互性强、真实感强、经济适用性强等特点有效的弥补了传统虚拟展示、地图领域不够逼真等缺陷。让失物信息直接在全景图上标注出地址和物品信息，让用户根据建筑物的地理信息快速找到丢失物品，系统再结合线上广泛传播和线下认领的方式，提高了寻物效率。

Abstract： The traditional way of managing lost property and founding mainly relies on manual paper records. With the continuous advancement of lost information and the construction of network information， it is obviously unable to meet the increasing demand for management. To this end， we have designed a Lost and Found platform that includes a lost information release function， an item claim function， and a panorama online search function collection. Its biggest difference from the traditional online lost and found platform is the addition of panorama mode， because it skillfully combines virtual reality technology， digital image processing technology， computer graphics and multimedia technology and other information technologies， with strong human-computer interaction. The characteristics of strong sense of reality， strong economic applicability and other features have effectively compensated for defects such as the traditional virtual display and the lack of realism in the map field. Let the lost information directly indicate the address and item information on the panorama， allowing the user to quickly find the lost items based on the geographical information of the building. The system then combines the methods of wide spread and offline claims on the line to improve the search efficiency.

Key words： lost and found platform； panorama technology； virtual reality technology； strong interactivity； improve the efficiency of searching

1 背景

該系统是结合虚拟现实的全景图技术设计的一款失物招领系统软件。前端基于three.js制作全景图以及部分用户数据的采集，后台采用PHP开发技术的失物招领平台。将ThinkPHP开源框架与HTML、JavaScript等技术结合来实现地理位置信息的记录，物品信息的记录以及发布物品信息功能。在该失物招领平台上用户可以在全景图中根据标记地理位置信息来寻找物品信息，以此提高物品寻找效率。
